Remember when all Harry had to worry about at Hogwarts was whether Voldemort lived in his teacher's turban? This week, Umbridge makes an impression; Ron makes the team; Hermione makes hats; no one seems to make any dent in their insane piles of homework; and Percy and Sirius make us furious. We forgive Sirius though, because wow, does that guy have it rough. Plus: Where do the vanished snails go?! This week's chapters: Detention with Dolores & Percy and Padfoot Next week's chapters: The Hogwarts High Inquisitor & In the Hog's Head
